Golf club head structure

ABSTRACT

A golf club head consists of a shell part, and a face part; the shell part has a front opening, a holding hollowness behind the front opening, several strengthening pieces in the holding hollowness, and a slot on an upper side, which communicates with the holding hollowness; the slot of the shell part has several connecting blocks therein, which are each connected to two lateral sides of the slot, for increasing capability of the shell part to bear force; the face part is closely fitted in the front opening of the shell part, and propped by means of the strengthening pieces in the holding hollowness; and, a kind of elastic shock absorbing material is injected in the holding hollowness of the shell part to prop the face part.

BACKGROUND OF THE INVENTION

1. Field of the invention

The present invention relates to a golf club head, more particularlyone, which will help a golfer make a golf ball fly smoothly, and reducereaction of the golf ball, thus preventing the golfer's hands from beingsubjected to shock, discomfort and injury.

2. Brief Description of the Prior Art

Referring to FIG. 1, a conventional golf club head consists of a shellpart 91, and a face part 92. The shell part 91 is made of metallicmaterials such as stainless steel by means of casting. The shell part 91has a front opening 911, a truncated cone shaped inner circumferentialside around the front opening 911, a holding hollowness 912 behind thefront opening 911, and a protruding portion 913 on an inward portion ofthe truncated cone shaped inner circumferential side. The face part 92is secured in the front opening 911 of the shell part 91, closelytouching the truncated cone shaped inner circumferential side and beingpropped by means of the protruding portion 913.

The above structure has the following disadvantages:

1. Because both the golf club head and golf balls are very hard, and theclub head doesn't have any shock absorbing function, a golf ball willprobably fly non-smoothly and in a wrong direction even if the golferswings the golf club to hit the golf ball in a correct way. In otherwords, it is relatively difficult to make an accurate golf shot with thegolf club.

2. When a golfer hits a golf ball with the golf club, the reaction ofthe golf ball on the club will be passed on to and cause discomfort andeven injury to the golfer's hands because the club head doesn't have anyshock absorbing function. In other words, the golf club isn't relativelysafe to use.

SUMMARY OF THE INVENTION

It is a main object of the invention to provide an improvement on a golfclub head to overcome the above-mentioned problems.

The golf club head of the present invention consists of a shell part,and a face part. The shell part has a front opening, a holdinghollowness behind the front opening, a few strengthening pieces in theholding hollowness, and a slot on an upper side thereof, whichcommunicates with the holding hollowness. The shell part further hasseveral connecting blocks, which are received in the slot, and eachconnected to two lateral sides of the slot, for increasing capability ofthe club head to bear force. The face part is closely fitted in thefront opening of the shell part, and propped by means of thestrengthening pieces in the holding hollowness. Furthermore, a kind ofelastic shock absorbing material is injected in the holding hollownessof the shell part to prop the face part. Because the club head has shockabsorbing function with the elastic shock absorbing material, the golfball will fly smoothly if a golfer swings the golf club to hit a golfball in a correct way. And, the reaction of the golf ball will besignificantly reduced, prevented from causing discomfort and injury tothe golfer's hands.

BRIEF DESCRIPTION OF THE DRAWINGS

The present invention will be better understood by referring to theaccompanying drawings, wherein:

FIG. 1 is an exploded perspective view of the prior art,

FIG. 2 is an exploded perspective view of the present invention,

FIG. 3 is a horizontal sectional view of the present invention, and

FIG. 4 is a vertical sectional view of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 2 to 4, a preferred embodiment of a head of a golfclub consists of a shell part 1, and a face part 2. The shell part 1 ismade of metallic materials, e.g. stainless steel, by means of casting.The shell part 1 has a front opening 11, a truncated cone shaped innercircumferential side around the front opening 11, a holding hollowness12 behind the front opening 11, and a protruding portion 13 on an inwardend of the truncated cone shaped inner circumferential side.Furthermore, the shell part 1 has a slot 14 on an upper side thereof,which communicates with the holding hollowness 12. The slot 14 hasseveral connecting blocks 15 therein, which are each connected to twolateral sides of the slot 14. A few strengthening pieces 16 are held inthe holding hollowness 12. Therefore, the upper portion of the clubhead, on which the slot 14 and the connecting blocks 15 are provided,can bear more force, preventing damage and deformation to the club headif the golf club head collides with a golf ball at the upper portion.

The face part 2 is secured in the front opening 11 of the shell part 1,closely touching the truncated cone shaped inner circumferential sideand being propped by means of the protruding portion 13 as well as thestrengthening pieces 16. Furthermore, a kind of elastic shock absorbingmaterial 3, e.g. resin, is injected in the holding hollowness 12 of theshell part 1 through the slot 14 so that the holding hollowness 12 isfilled with the shock absorbing material 3, and the face part 2 ispropped by the shock absorbing material 3. Finally, the shell part 1 ispolished, and joined to a shaft part of the golf club.

From the above description, it can be seen that the present inventionhas the following advantages over the prior art:

1. It will be easier to make a golf ball fly smoothly and in the correctdirection with the golf club of the present invention because the clubhead is filled with a shock absorbing material. In other words, there ismore chance of a golfer making a good shot with the golf club of thepresent invention.

2. Because the club head of the present invention is filled with a shockabsorbing material, which also props the face part of the club head, alarge proportion of the reaction of a golf ball will be absorbed bymeans of the shock absorbing material when the club heads collides withthe golf ball, thus preventing discomfort and injury to the golfer'shands.

1. An improvement on a golf club head structure, comprising a shellpart, the shell part having a front opening, and a holding hollownessbehind the front opening; the shell part having a slot on one sidethereof; the slot communicating with the holding hollowness; a face partclosely fitted and secured in the front opening of the shell part; and akind of elastic shock absorbing material injected in the holdinghollowness of the shell part.
 2. The improvement on a golf club headstructure as recited in claim 1, wherein the slot of the shell part hasa plurality of connecting blocks therein, which are each connected totwo lateral sides of the slot, for increasing capability of the shellpart to bear force.
 3. The improvement on a golf club head structure asrecited in claim 1 further having a plurality of strengthening piecesheld in the holding hollowness of the shell part and propping the facepart.
 4. The improvement on a golf club head structure as recited inclaim 1, wherein the elastic shock absorbing material is resin.
